of eye injury, always wear ANSI Z87.1 approved eye
protection when performing thisprocedure.
WARNING: Never use solvents or other harsh
chemicals for cleaning the non‑metallic parts of the
tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with
water and mild soap. Never let any liquid get inside the
tool; never immerse any part of the tool into aliquid.

over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper tool
care and regularcleaning.
Hammerdrilling DCD805
IMPORTANT: Use carbide-tipped or masonry bits rated for
percussion drillingonly.
1. Select the desired speed/torque range using the speed
selector
8
to match the speed and torque to the
planned operation. Turn the mode selection collar
5
to
the hammerdrillsymbol.
2. Pull the trigger, applying just enough pressure on the
hammer to keep it from bouncing excessively or "rising"
off the bit.
Recommendations for Hammerdrilling
• Too much force will cause slower drilling speeds,
overheating, and a lower drillingrate.
• A smooth even flow of material indicates the proper
drillingrate.
• Drill straight, keeping the bit at a right angle to the work.
Do not exert side pressure on the bit when drillling as
this will cause clogging of the bit flutes and a slower
drillingspeed.
• When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with tool still
running to help clear debris from thehole.
Screwdriving
Your tool has a clutch with adjustable torque for driving
and removing a wide array of fastener shapes and sizes. The
numbers 1–15 on the mode selection collar
5
are used to
set a torque range for screwdriving. The higher the number
on the collar, the higher the torque and the larger the
fastener which can bedriven.
1. Turn the mode selection collar
5
to the desiredposition.
Refer to Mode Selection.
2. Pull the trigger switch applying pressure in a straight line
with the bit until the fastener is seated at the desired
depth in theworkpiece.
Recommendations for Screwdriving
• Start with lower torque settings, then advance to higher
torque settings to avoid damage to the workpiece
orfastener.
• Make some practice runs in scrap or on unseen areas of
the workpiece to determine the proper position of the
mode selectioncollar.
Drilling
IMPORTANT: For MASONRY, such as brick, cement, cinder
block, etc., use carbide-tipped masonrybits.
1. Turn the mode selection collar
5
to the drillsymbol.
Refer to ModeSelection.
2. Place drill bit in contact with theworkpiece.
NOTE: Use sharp drill bitonly.
3. Pull the trigger switch applying pressure in a straight line
with the bit until it reaches the desireddepth.
WARNING: Drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill
firmly to control the twisting action and avoidinjury.
4. Keep the motor running when pulling the bit back out of
a drilled hole to preventjamming.
Recommendations for Drilling
• When drilling, always apply pressure in a straight line
with the bit, but do not push hard enough to stall the
motor or deflect thebit.
• IF THE DRILL STALLS:
- RELEASE TRIGGER SWITCH IMMEDIATELY,
remove drill bit from work, and determine cause
ofstalling.
‑ DO NOT DEPRESS TRIGGER SWITCH ON AND OFF
IN AN ATTEMPT TO START A STALLED DRILL—
THIS CAN DAMAGE THEDRILL.
‑ To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of thehole.
• Large holes (5/16" to 1/2" [7.9 mm to 12.7 mm]) in steel
can be made easier if a pilot hole (5/32" to 3/16" [4 mm
to 4.8 mm]) is drilledfirst.
• If drilling thin material or material that is prone to splinter,
use a wood “back-up” block to prevent damage to
theworkpiece.
